fcntl: skip F_GETLK64, F_SETLK64, and F_SETLKW64 in fcntl syscall parser
As the kernel recognizes F_GETLK64, F_SETLK64, and F_SETLKW64 commands
in fcntl64 syscall only, do not parse their structures in fcntl parser.
* xlat/fcntlcmds.in: Move F_GETLK64, F_SETLK64, and F_SETLKW64 ...
* xlat/fcntl64cmds.in: ... here.
* fcntl.c: Include "xlat/fcntl64cmds.h".
(print_fcntl): Move printing of first two syscall arguments
and handling of F_GETLK64, F_SETLK64, and F_SETLKW64 commands ...
(SYS_FUNC(fcntl), SYS_FUNC(fcntl64)): ... here.
* tests/fcntl.c: New file, based on struct_flock.c.
* tests/fcntl64.c: Likewise.
* tests/struct_flock.c (test_flock_einval, create_sample): New functions.
(test_flock): Use test_flock_einval.
(test_flock64, main): Remove.
* tests/fcntl.test: New test.
* tests/fcntl64.test: Likewise.
* tests/struct_flock.test: Remove.
* tests/Makefile.am (check_PROGRAMS): Add fcntl and fcntl64,
remove struct_flock.
(TESTS): Add fcntl.test and fcntl64.test, remove struct_flock.test.
(EXTRA_DIST) Add struct_flock.c.
* tests/.gitignore: Add fcntl and fcntl64, remove struct_flock.
